The plant based raw material (1) is fed to the first enzymatic hydrolysis stage (2), the plant based raw material (1) is hydrolysed in at least two enzymatic hydrolysis stages (2,4), a liquid fraction (5a,5b) comprising carbohydrates is separated from a solid fraction (6a,6b) in a solid-liquid separation stage (7a,7b) after each enzymatic hydrolysis stage (2,4), and the solid fraction (6a) is supplied to the next enzymatic hydrolysis stage (4) in which the solid fraction is treated, and the solid fraction (6b) is recovered after the last solid-liquid separation stage (7b). Further, the invention relates to the liquid fraction and the solid fraction and their use.
